Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Prolonged febrile seizures can affect pediatric patients

A long-standing hypothesis holds that prolonged febrile (fever induced) seizures, the most common form of childhood convulsive status epilepticus, cause mesial temporal sclerosis. CSE is a single seizure, or two or more seizures between which consciousness is not regained, lasting for more than 30 minutes.

MRI-guided SLA surgery proves safe and shows adequate efficacy for seizure control

MRI-Guided Stereotactic Laser Ablation of the hippocampus to control seizures in people with temporal lobe epilepsy may result in seizure control that approaches that from anterior temporal lobectory or selective amygdalohippocampectomy and better cognitive outcomes than any of the standard open resections, according to a study presented at the American Epilepsy Society's 67th Annual Meeting in Washington DC.

Research roundup: 'Substantial' Medicare savings from avoiding ERs; new ways for primary care; trends in kids' fast food consumption

Some Medicare beneficiaries who place 911 calls to request an ambulance might safely be cared for in settings other than the emergency department at lower cost. Using 2005–09 Medicare claims data and a validated algorithm, we estimated that 12.9–16.2 percent of Medicare-covered 911 emergency medical services transports involved conditions that were probably nonemergent or primary care treatable.

Underlying loss of awareness during partial seizures is same as deep sleep

Epilepsy patients with complex partial seizures have impaired consciousness during seizure episodes and typically have no memory of the event. However, the mechanisms of seizure unconsciousness are unclear.

Scientists receive 2013 Horwitz Prize for discoveries on how brain calculates location, navigation

Edvard and May-Britt Moser of the Norwegian University of Science and Technology (NTNU), and John O'Keefe, from University College London have been awarded the 2013 Louisa Gross Horwitz Prize for discoveries that have illuminated how the brain calculates location and navigation.

Downregulation of caveolin-1 contributes to synaptic plasticity deficit in hippocampus of aged rats

Caveolin-1 may be a new target for interfering with age-dependent decline in synaptic plasticity. To explore the relationship between synaptic plasticity in the aging process and changes in learning and memory, Dr. Yang Liu and coworkers from the First Affiliated Hospital, Dalian Medical University, China examined synaptophysin expression in the hippocampus, cortex and cerebellum of rats at different ages, and analyzed the association between synaptophysin expression and cognition and behaviors.

Scientists receive 2013 Louisa Gross Horwitz Prize for advancements in field of neuroscience

For discoveries about how the brain calculates and remembers where it is—which could be part of the foundation of memory—Columbia University will award the 2013 Louisa Gross Horwitz Prize to Edvard I. Moser, PhD, and May-Britt Moser, PhD, of the Norwegian University of Science and Technology in Norway, and John Michael O'Keefe, PhD, of University College London in the UK.

Biologists discover how nerve cells recycle tiny vesicles

University of Utah and German biologists discovered how nerve cells recycle tiny bubbles or "vesicles" that send chemical nerve signals from one cell to the next. The process is much faster and different than two previously proposed mechanisms for recycling the bubbles.

Researchers discover how PC7 protein affects certain types of cognitive performance

A team of Montr-al researchers at the IRCM led by Dr. Nabil G. Seidah, in collaboration with Dr. William C. Wetsel's team at Duke University in the United States, discovered that the protein PC7 plays a critical role in the brain by affecting certain types of cognitive performance such as anxiety, learning and emotional memory. Their results, recently published in the scientific journals Proceedings of the National Academy of Sciences (PNAS) and Nature, could have a significant impact on regulating behaviour related to anxiety disorders and trauma.

Cognitive behavioral therapy for PTSD affects underlying biology of the disorder

A new paper published in Biological Psychiatry suggests that cognitive behavioral therapy for posttraumatic stress disorder not only reduces symptoms but also affects the underlying biology of this disorder.

Scientists identify enzyme that could lead to better treatment of Alzheimer's disease

St. Jude Children's Research Hospital scientists have identified an enzyme that can halt or possibly even reverse the build-up of toxic protein fragments known as plaques in the brains of mice with Alzheimer's disease. The research appeared in a recent edition of the scientific journal Nature Communications.

Certain hormones which are increased during exercise may help improve memory

Researchers at Boston University School of Medicine (BUSM) have found further evidence that exercise may be beneficial for brain health and cognition. The findings, which are currently available online in Behavioural Brain Research, suggest that certain hormones, which are increased during exercise, may help improve memory.

Neuroscientists discover how brain cells form "geotags" for specific memories

Using a video game in which people navigate through a virtual town delivering objects to specific locations, a team of neuroscientists from the University of Pennsylvania and Freiburg University has discovered how brain cells that encode spatial information form "geotags" for specific memories and are activated immediately before those memories are recalled.

Researchers identify gene responsible for malfunctions in fear-related memory system

A study published recently in the Journal of Neuroscience points, for the first time, to the gene trkC as a factor in susceptibility to the disease. The researchers define the specific mechanism for the formation of fear memories which will help in the development of new pharmacological and cognitive treatments.

Study finds patients with focal epilepsy have widespread, abnormal connections in their brains

Patients with the most common form of focal epilepsy have widespread, abnormal connections in their brains that could provide clues toward diagnosis and treatment, according to a new study published online in the journal Radiology.

BIDMC pilot study shows promise for age-related cognitive disorders

It's well known that the brains of meditators change, but it's not entirely clear what those changes mean or how the changes might benefit the meditator. A new pilot study led by researchers at Beth Israel Deaconess Medical Center suggests that the brain changes associated with meditation and stress reduction may play an important role in slowing the progression of age-related cognitive disorders like Alzheimer's disease and other dementias.

Research could refine next generation of drugs to help treat dementia

A £1.1 million grant to understand how one of the brain's key neurotransmitters called 'acetylcholine' influences brain activity has been awarded to University of Bristol researchers. The Wellcome Trust award will help scientists understand more precisely how the release of acetylcholine is changing brain cell activity to influence memory and cognition.

Aerobic exercise helps healthy aging adults improve memory, brain health and physical fitness

A new study conducted by researchers at the Center for BrainHealth at The University of Texas at Dallas published online in the open-access journal Frontiers in Aging Neuroscience found that engaging in a physical exercise regimen helps healthy aging adults improve their memory, brain health and physical fitness.
